Can you pluck one of the leaves from the plant and take a picture of it under natural light? That will help us in determining what is happening with your plant.

Thank you very much. ✌️🫡

I'm not sure. You appear to have an N deficiency but hard to tell as the colour was all washed out in your pic.

An N deficiency can result from moving from veg to bloom nutes too soon after flipping. I wait for first preflower and then transition them over a couple of weeks.

You could be Potassium deficient also which is easy to mistake for nute burn so I'd take an approach for one thing at a time..lights raised done, now fix one or two of your nutes then suppliment if necessary.

[Gaz21]

1 week after flip. So is it calmag deficiency?? IYO

[Bluey]

Yes they can act differently.

Give your plants an additional cal/mag suppliment like calimagic.

When did you stop veg nutes and start flower nutes relative to the flip?

[Gaz21]

Thankyou for your replies. I'm sorry about the pictures. The problem seems to be getting worse now. It's like there is lots going on. In my limited knowledge. It's only one plant though. Can one plant out of 4 clones from the same mother react differently,in the exact same environment? Sorry for the extra question

[Rootsruler]

Agreed! You say you backed off the light to 850 umol but 850 umol is pretty high so if you backed it off from there my guess is they got light stress.

[Bluey]

It's really hard to tell from those pics.
Nute burn is a browning of the leaf tips, they often curl up and the brown spreads a little down the margins of the leaf.
Nute deficiency is a yellowing or lightening of the tips, which can also indicate light burn and is often combined with heat stress.
I think you may have had some light stress.
Those dark lines down the middle of the leaf, is that normal for those plants, if not, it could be copper or calcium deficiency BUT I can't see any other symptoms so I doubt it.
We need much better pics.

[Gaz21]

Please help
I'm suspecting this is nute burn. And maybe some light stress because the leaves are a little yellowish compared to the other 3 plants. (am I right?) But what confuses me is that I have four plants from the same mother. All getting fed from the same rez in autopots.. if its nute burn then how come it's only one plant???
4 super buff cherry-auto pot system- coco- mid 5th week of flowering. Temp 25.5 C / RH 48. PH 6.1 Ec 2.1 in the rez Daylight 600w pro.. I've backed off nutes and raised lights a little to 850 umols. Also what confuses me is that this plant is further from the light than the other 3 and they look brilliant. Please any opinion I will be thankful for.

Thanks for your comments! I will transplant her to the final fabric pot later today.

[Rootsruler]

Relax. Nothing out of the ordinary. As Bluey mentioned, they look like they're fine. Sometimes leaves get weird. What's important to note is the new growth.

[Bluey]

What would I do?

They look happy.

I'd probably get them into their final resting place, triple check the pH I was giving them with an accurate pH meter, check light intensity and environment and double check nute dosage.

Then I'd chill and smoke a big fat number.

[folder52]

Hey guys, some new fotos. I think it's getting worse. Not it's not just yellow dots, but also yellow lines

[Rootsruler]

Agree. Media looks saturated. It's probably some water or nutrient solution that got splashed on the leaf.

[Bluey]

They look good apart from the yellow spot.

No idea what it is.

Try wiping it off.

Medium looks very wet but plant looks happy.
